What is polyimide Kapton?
Kapton is a polyimide film developed by DuPont in the late 1960s that remains stable (in isolation) across a wide range of temperatures, from −269 to +400 °C (−452 to 752 °F; 4 to 673 K). The ring closure is carried out at high temperatures of 200–300 °C (392–572 °F; 473–573 K).
What is Kapton film used for?
Electronics Manufacturing Due to its electrical insulation ability and temperature stability, Kapton® has long served a useful purpose in electronic manufacturing. The film typically acts as an insulation and protection layer on electrostatic sensitive and fragile components.
Is polyimide tape the same as Kapton tape?
Adhesive Polyimide Tape and Kapton Tape are not the same thing. For a tape to be called Kapton Tape, it must use DuPont™ Kapton® in its construction. Kapton is a registered trademark of DuPont so for any tape to carry that designation, it must use their product (fair enough really).
What is Kapton film made of?
Kapton Tape is made from DuPont Kapton® HN general purpose film with silicon adhesive. It has been used in applications at temperatures as low as -269°C (-452°F) and as high as 260°C (500°F).
Is Kapton a polyimide?
Kapton® FWR A tough, high dielectric strength insulation with improved hydrolysis resistance versus commonly used polyimide containing materials.
Is Kapton electrically conductive?
DuPont™ Kapton® RS is an electrically conductive polyimide film developed for heating applications where a thin, lightweight, uniform heater is needed.
What is special about Kapton tape?
It’s heat and chemical resistant, it’s strong, and it’s available in very thin sheets. On top of that, Kapton tape provides electrical insulation, and has a low outgassing rate, making it great for high-vacuum applications. Kapton tape has excellent adhesion properties and leaves nothing behind when peeled off.
Who manufactures Kapton tape?
Dupont
1Mil Kapton tape is developed by Dupont which is a HN general purpose film with silicon adhesive. Kapton polyimide films shows excellent electrical insulation properties, high temperature resistant, and excellent solvent resistant.
Who invented Kapton?
DuPont
Kapton® is a unique polyimide film that was invented and trademarked by DuPont in the 1960s. Over the years, it has proven its viability as the best flexible material of choice in applications involving extreme temperature variations.
Is Kapton flammable?
Kapton® film has the highest UL-94 flammability rating of V-0. Additionally, the material does not burn and has no known melting point. The exceptional dielectric strength of Kapton® film makes it the perfect material for thin electrical insulation uses.
Is Kapton tape safe?
RocketSled. Material Data Safety Sheet for Kapton. Basically: no risk for ingestion.
What can I use instead of Kapton tape?
Polyimide Film Tape (7000X) is a electrical grade Kapton™ alternative Polymide film coated with a high performance silicone adhesive.
What kind of material is Kapton polyimide made of?
Kapton® polyimide film is synthesized by polymerizing an aromatic dianhydride and an aromatic diamine. This material offers outstanding longevitiy and is hightly resistant to an extremely wide temperature range (-269°C to 400°C).
Which is the best Kapton film to use?
Kapton® GS film has been specifically designed and manufactured to expand the processing window and improve yields during artificial graphite sheet production. Kapton® HN is the recommended choice for applications that require an all-polyimide film with an excellent balance of properties over a wide range of temperatures.
Why are Kapton polyimide films used in magnet wire?
DuPont™ Kapton® 150PRN411 is ideal for insulating copper conductor used in high temperature magnet wire applications. Kapton® PST is a tough film that exhibits an excellent balance of physical, chemical and electrical properties over a wide temperature range, particularly at unusually high temperatures.
What are some of the properties of Kapton?
Kapton is an aromatic polyimide with outstanding thermal and dielectric properties. It can do things few other plastics can do, like withstand temperatures from nearly absolute zero to 400 °C.
